Description

Technical Field

[0001] This utility model relates to the field of agricultural product drying technology, and in particular to a hot air distributor for drying tea. Background Technology

[0002] Tea, generally referring to the leaves and buds of the tea tree (Camellia sinensis), a plant belonging to the genus Camellia in the family Theaceae, is rich in catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid. Modern research has confirmed its multiple health benefits. As a landmark crop originating in China, the history of tea utilization shows a clear evolutionary trajectory. Initially used as a sacrificial offering, tea gradually entered the food and beverage field as a dish in the late Spring and Autumn Period. By the mid-Western Han Dynasty, its use had expanded to the medicinal realm. In the late Western Han Dynasty, it became an exclusive beverage for the imperial court. Its popularization among the common people as a daily drink began after the Western Jin Dynasty. In tea processing, drying is a crucial step. Its core purpose is to remove excess moisture from the tea leaves, terminate the internal biochemical reactions, and fix the quality characteristics of the tea. To improve processing efficiency while ensuring tea quality, modern tea drying often uses mechanical equipment.

[0003] Hot air drying is a widely used drying method in tea processing. Its core principle is to use heated flowing air as a heat transfer medium to evaporate and remove the moisture in the tea leaves through thermal convection, thereby achieving the purpose of drying. In order to ensure that the tea leaves can be heated evenly and improve the drying quality and efficiency, a hot air distributor is often used to distribute the hot air generated by the hot air blower evenly into the drying chamber. However, existing hot air distributors cannot evenly adjust the air volume of each air outlet, resulting in uneven adjustment when the air volume is adjusted, which affects the average quality of the tea leaves. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hot air distributor for drying tea, which aims to improve the problem of uneven adjustment when adjusting the air volume in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot air distributor for drying tea leaves, comprising a hollow shell, with multiple air outlets on the right side of the outer wall of the hollow shell, ventilation pipes fixedly connected to the inner wall of the air outlets, multiple limiting grooves in the middle of the outer wall of the hollow shell, a rotating disk rotatably connected to the inner wall of the limiting grooves, multiple adjustment holes on the left side of the rotating disk, a ventilation plate one fixedly connected to the middle of the inner wall of the hollow shell, multiple ventilation holes one on the left side of the ventilation plate one, a ventilation plate two fixedly connected to the right side of the inner wall of the hollow shell, multiple ventilation holes two on the left side of the ventilation plate two, and a quick-release mechanism connected to the left side of the inner wall of the hollow shell near the edge, the quick-release mechanism being used for quick installation and disassembly.

[0006] As a further description of the above technical solution:

[0007] The quick-release mechanism includes a fixed chuck, with multiple locking rods fixedly connected to the outer wall of the fixed chuck. A ventilation hose is provided on the left side of the fixed chuck, with fixed sleeves fixedly connected to both ends of the ventilation hose. Multiple springs are fixedly connected to adjacent sides of the fixed sleeves, and sliding sleeves are fixedly connected to adjacent sides of the springs. Multiple sliding chucks are slidably connected to the outer wall of the ventilation hose, and locking grooves are provided on the far sides of the sliding chucks.

[0008] As a further description of the above technical solution:

[0009] A fan housing is fixedly connected to the left side of the inner wall of the hollow shell, and a fan cover is fixedly connected to the left side of the inner wall of the fan housing.

[0010] As a further description of the above technical solution:

[0011] A fan cover is fixedly connected to the right side of the inner wall of the fan housing, and a protective cover is fixedly connected to the left side of the fan cover.

[0012] As a further description of the above technical solution:

[0013] A motor is fixedly connected to the inner wall of the protective cover, and a fan blade is fixedly connected to the output end of the motor.

[0014] As a further description of the above technical solution:

[0015] A sealing gasket is fixedly connected to the right side of the ventilation panel one, and a sealing gasket is fixedly connected to the left side of the ventilation panel two.

[0016] As a further description of the above technical solution:

[0017] A first air guide plate is fixedly connected to the left side of the first ventilation plate, and a second air guide plate is fixedly connected to the middle of the inner wall of the hollow shell near the edge.

[0018] As a further description of the above technical solution:

[0019] A handle is fixedly connected to the top of the outer wall of the rotating disk, and the inner wall of the second ventilation hole is fixedly connected to the outer wall of the ventilation pipe.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the operator can change the hot air passage area by rotating the rotating disc. When the adjustment hole coincides with the positions of ventilation hole one and ventilation plate two, the ventilation area is the largest and the wind speed is the smallest. Rotating the rotating disc reduces the ventilation area and increases the wind speed. This adjustment can achieve the same change in the wind speed of each ventilation pipe, achieving uniform distribution of hot air. It solves the problem of uneven adjustment when adjusting the air volume, and avoids uneven drying of tea leaves due to excessive or insufficient local air volume, such as some tea leaves being scorched and some tea leaves not being completely dried. This effectively ensures the quality and consistency of tea drying and enhances the commercial value of tea.

[0022] 2. In this utility model, the locking groove is aligned with the locking rod, the sliding chuck is pushed to compress the spring, and then the sliding chuck is rotated to lock itself, thus completing the connection of the ventilation hose. When disassembling, the sliding chuck is pressed and rotated. This convenient and stable connection method greatly shortens the time for connecting and disassembling the equipment, reduces the downtime caused by changing the air source and maintaining the equipment, and improves the utilization rate and production efficiency of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 This utility model provides an embodiment of a hot air distributor for drying tea leaves, comprising a hollow shell 1, a plurality of air outlets 4 on the right side of the outer wall of the hollow shell 1, a ventilation pipe 3 fixedly connected to the inner wall of the air outlets 4, a plurality of limiting grooves 22 in the middle of the outer wall of the hollow shell 1, a rotating disk 5 rotatably connected to the inner wall of the limiting grooves 22, a plurality of adjusting holes 6 on the left side of the rotating disk 5, a ventilation plate 7 fixedly connected to the middle of the inner wall of the hollow shell 1, a plurality of ventilation holes 8 on the left side of the ventilation plate 7, a ventilation plate 9 fixedly connected to the right side of the inner wall of the hollow shell 1, a plurality of ventilation holes 10 on the left side of the ventilation plate 9, and a quick-release mechanism 2 connected to the left side of the inner wall of the hollow shell 1 near the edge, the quick-release mechanism 2 being used for quick installation and disassembly;

[0032] Specifically, the hollow shell 1 serves as the main frame of the entire hot air distributor, providing a mounting base for other components and forming a relatively enclosed space. This allows the hot air to flow inside according to the designed path, while also providing a certain degree of insulation to reduce heat loss. The ventilation duct 3 delivers the distributed and adjusted hot air to the tea drying area, achieving directional delivery of the hot air. The ventilation plate 1 7 enables the initial passage and distribution of the hot air, and the ventilation plate 2 9 distributes the adjusted hot air to each ventilation duct 3.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3The quick-release mechanism 2 includes a fixed chuck 201, with multiple locking rods 202 fixedly connected to the outer wall of the fixed chuck 201. A ventilation hose 208 is provided on the left side of the fixed chuck 201. Fixed sleeves 205 are fixedly connected to both ends of the ventilation hose 208. Multiple springs 206 are fixedly connected to the adjacent sides of the fixed sleeves 205. Sliding sleeves 207 are fixedly connected to the adjacent sides of the springs 206. Multiple sliding chucks 203 are slidably connected to the outer wall of the ventilation hose 208. Locking grooves 204 are provided on the far sides of the sliding chucks 203.

[0034] Specifically, the fixed chuck 201 is the basic fixed component of the quick-release mechanism 2. The locking rod 202 on the outer wall is used to cooperate with the sliding chuck 203 to achieve quick connection and disassembly. The function of the spring 206 is to lock the locking rod 202 to ensure the connection is stable. The ventilation hose 208 is used to connect the hollow shell 1 and the external air source to introduce hot air into the hollow shell 1. At the same time, it has heat preservation capabilities to reduce heat loss.

[0035] Please see the appendix Figure 1 and attached Figure 5 A fan housing 16 is fixedly connected to the left side of the inner wall of the hollow housing 1. A second fan cover 18 is fixedly connected to the left side of the inner wall of the fan housing 16. A first fan cover 17 is fixedly connected to the right side of the inner wall of the fan housing 16. A protective cover 19 is fixedly connected to the left side of the first fan cover 17. A motor 20 is fixedly connected to the inner wall of the protective cover 19. A fan blade 21 is fixedly connected to the output end of the motor 20.

[0036] Specifically, fan cover 17, fan cover 2 18, and fan housing 16 together form a relatively enclosed space, providing stable support and fixation for motor 20 and fan blades 21, while also playing a certain protective role. Protective cover 19 prevents motor 20 from being hit and damaged by external objects during operation, and also prevents impurities from entering the interior of motor 20, thus extending the service life of motor 20. The model of motor 20 is YU7124.

[0037] Please see the appendix Figure 1 and Figure 4 A sealing gasket 12 is fixedly connected to the right side of ventilation plate 1 7, a sealing gasket 2 13 is fixedly connected to the left side of ventilation plate 2 9, a guide plate 14 is fixedly connected to the left side of ventilation plate 1 7, a guide plate 2 15 is fixedly connected to the middle of the inner wall of hollow shell 1 near the edge, a handle 11 is fixedly connected to the top of the outer wall of rotating disk 5, and the inner wall of ventilation hole 2 10 is fixedly connected to the outer wall of ventilation pipe 3.

[0038] Specifically, sealing gasket 12 and sealing gasket 23 prevent hot air from leaking from the gap between the ventilation plate and the hollow shell 1 during the flow process, ensuring that the hot air can flow along the designed path and improving the hot air distribution efficiency. Air guide plate 14 and air guide plate 25 guide the hot air, making the hot air flow more evenly in the hollow shell 1, improving the effect of air volume regulation and the uniformity of hot air distribution.

[0039] Working principle: When the operator needs to adjust the air volume, it can be achieved by rotating the rotating disk 5. After rotating the rotating disk 5, the area through which the hot air passes will change uniformly. When the position of the adjustment hole 6 coincides with the position of the ventilation hole 1 8 and the ventilation plate 2 9, the ventilation area is the largest and the wind speed is the smallest. After rotating the rotating disk 5, the adjustment hole 6 rotates accordingly, the ventilation area will decrease and the wind speed will decrease. This can achieve equal adjustment of the air outlet wind speed of each ventilation pipe 3 and achieve uniform distribution of hot air.

[0040] When the operator needs to connect the air source, first connect one end of the ventilation hose 208 to the hollow housing 1. During the connection process, simply align the locking groove 204 with the locking rod 202, and then push the sliding chuck 203 against the fixed chuck 201 to compress the spring 206. At this time, rotate the sliding chuck 203 to lock the locking rod 202 into the locking groove 204. Since the spring 206 is in a compressed state, it can effectively lock the locking rod 202. When disassembling, simply press the sliding chuck 203 and rotate it. The operation is the same when connecting the air source.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
